How do you feel the joke that the earth goes round?

With the concept of gravity, people will not make a fuss about people standing "head down" on the back of the earth. For people on the surface of the earth, "below" is the direction of gravity, that is, pointing to the center of the earth. The gravity given to us by the earth allows us to walk and jump freely without worrying about falling into the sky. Even if the earth has an amazing rotation speed, it can't overcome gravity and throw people into the sky. Every day, the sun rises in the east, slowly crosses a wonderful arc in the sky, and finally disappears in the west. The earth under our feet seems to be very stable, and the object that has been moving is the big disk that emits strong light overhead. Now we know that the earth is huge, but the sun is by no means as small as it looks. It is much bigger than the earth. If you choose to keep the earth still, then the sun must revolve around the earth once a day, so that the huge sun can revolve around the small earth at a high speed. Is this picture ridiculous? It seems more logical to make the earth move. The earth rotates from west to east, driving mountains, rivers, atmosphere and biological Qi Fei. Because of the same movement, we can't feel the earth spinning. What we see is that the sun in the sky keeps changing its position in one day and appears in the same position in the sky at almost the same time the next day. How can I feel the rotation of the earth? Starting from the gravity of the earth, we can determine the rotation of the earth by observing the earth from space. But we don't have to be so excited, we can prove the rotation of the earth on the surface of the earth.
